The Pila Mesh Home Battery plugs into a standard 120V wall outlet and does two jobs: it keeps high-draw essentials like your refrigerator running during outages, and it works with your solar and your utility rates to optimize your energy use the rest of the year.

Setup takes minutes – plug Pila into the wall, plug your appliances in, no electrician or rewiring. When the grid drops, Pila switches to battery automatically. Day to day, you get control over when energy is stored and used, plus real-time insights in the app.

Add more batteries anytime: they find each other over Pila's mesh network and run as one coordinated system across your home.

Traditional home batteries are large, permanent installations — expensive, invasive, and tied to a single electrical panel. Portable power stations are designed for occasional use and not built to live in your home. Pila sits in between: a persistent, plug-in home battery that lives with your appliances, automatically provides backup during outages, and intelligently manages energy day to day. No rewiring. No installation hassle.

The Pila Mesh Network is the magic behind how multiple Pila batteries seamlessly connect together, and allowing them to communicate with each other for coordinated battery control, plus a unified view of your home's energy. It is a secure, encrypted local network exclusive to your home, and it works even if Wi-Fi goes down to keep your home's energy smart and dependable.

Pila is currently available to customers in the United States and Puerto Rico.

We are not shipping internationally at this time, but encourage you to sign up for updates on new products and supported regions!

Setup is quick: place Pila next to the appliances and devices you want to back up – fridge, your media console and Wi-Fi router, your sump pump, your aquarium – plug Pila into a standard 120V wall outlet, then plug your appliances into Pila. That's the setup! Your Pila arrives at about 25% charge and tops up to full in under an hour on a standard outlet.

Connecting Pila to Wi-Fi and using the Pila App to finish setup ensures you always get the latest software updates and new features.

You'll use the free Pila App to get set up – it walks you through it in a few minutes, with no subscription or monthly fee. After that, the app is there when you want it: remote monitoring from anywhere, energy history over time, and advanced settings. But you're not tied to it.

Pila has an onboard screen for everyday use, backup works automatically whether the app is used or not, and once you're set up you can connect Home Assistant or other dashboards to monitor and control Pila your own way.

Place Pila batteries near the appliances you want to back up – your refrigerator, TV, networking gear, or home office. For multi-room coverage, one Pila per location is ideal.

Once it's placed, set-and-forget! Most people set Pila up once and never move it. Because it stays plugged in, Pila backs you up whether you're home or away. And over time it learns how your appliances behave – optimizing when energy is stored and used, and catching problems early, like a fridge that's starting to fail, before it spoils your food or becomes a costly repair. A portable power station is made to be carried to wherever you need a few hours of power. Pila is made to live with your appliances and work around the clock.

It depends on which appliances matter most to you. Most customers start with 2-4. Pila powers devices plugged directly into it, so you need one Pila per room. But even a single Pila is great for essentials like your fridge, Wi-Fi, and phone charging.

Yes. There's no technical limitation to plugging a standard power strip into one of Pila's outlets.

You may not need one, though. Pila has four outlets, each independently controllable, plus built-in surge and overload protection – the same protection most strips add. If you do use a power strip, keep the total draw of everything plugged into Pila within your wall outlet's continuous rating: typically 12-15A, or about 1400-1800W at 120V. Devices on the power strip share the single Pila outlet they're plugged into, so you'll control them as a group.

A single Pila battery keeps an average refrigerator powered for around 24-32 hours. With an Expansion Pack, that doubles to 64 hours. During an outage, Pila learns your appliances actual consumption and shows a real-time backup time forecast. Wi-Fi router: 132 hours. Lights: 158 hours. Laptop: 23 charges. Smartphone: 113 charges.

Learn more about what Pila can power here!

Pila powers most appliances that plug into a standard 120V outlet — refrigerators, Wi-Fi routers, TVs, laptops, phones, lamps, plug-in air conditioners, and sump pumps.

Continuous power limit is 2400W total.

Surge power limit is 3600W for 30 seconds.

Peak power handles 65A RMS startup surges.

Pila does not support 240V appliances like central AC or electric ranges.

When grid power is interrupted, Pila automatically switches to battery power in 20 milliseconds or less — no action needed from you. You'll be automatically notified when power is out via the Pila App, provided a personalized backup time forecast, and notified when utility power is restored.

When utility power is restored, Pila transitions back automatically and resumes charging and optimizing energy in the background for you.

Pila serves some of the same basic roles as an old-school UPS — automatic backup switchover, suitable for sensitive electronics. But the similarities end there...

A UPS is built for one job: bridge the gap for a single device when the power cuts, then go back to sitting idle. Pila works every day. It optimizes when your energy is stored and used, works with your solar and your utility rates to lower your bills, and learns your appliances well enough to catch a failing fridge before it spoils your food. Link several together over Pila's mesh network and that coverage extends across your whole home, all from standard outlets with no rewiring.

And while a UPS keeps small devices running for minutes, Pila is designed to power larger, essential household loads like refrigerators for many hours to days.

Generators require fuel, installation, and manual management. Pila provides clean, silent, instant backup with no fuel or installation required. You can also use both together — run appliances on Pila during an outage and use a generator to recharge it.

Pila charges three ways: from the grid through a standard wall outlet, from rooftop solar coordinated through your outlet, or directly from plug-in solar panels (Pila solar kits expected to start shipping later in 2026). From empty, a full recharge at max speed takes about an hour on a standard outlet.

Yes. Configure charge and discharge schedules in the Pila App to match your utility rate schedule — charge overnight when rates are low, discharge during peak hours.

Yes. Pila can be configured to automatically prioritize battery power even when the grid is available, to manage utility power bills and optimize home solar usage. Managed through the Pila App or onboard settings screen.

Rebate programs vary by region and utility. Check directly with your utility for current offerings. If Pila announces any utility partnerships, that information will be shared on our website.

Pila batteries use Lithium Iron Phosphate (LFP) cells — the same chemistry used in EVs and power tools, known for thermal stability and long cycle life. Rated for a 10-year lifetime under typical residential conditions.

With inverter on: under 10W. In dormant mode (inverter off): typically under 2W.

Under light loads (~500W or less), virtually silent. As load increases, fans become audible as a soft whirr from about 10 feet away. Fan noise is tuned toward lower frequencies to avoid high-pitched whine.

20 milliseconds or less — in practice typically below that. Well within what most modern electronics, networking gear, and computers can tolerate without even flickering.

Yes. Pila outputs pure sine wave AC – the same shape of power as your wall outlet – so sensitive electronics like computers and networking gear, and motor-driven appliances like your refrigerator, run on it normally. Its harmonic distortion sits in the same range as typical grid power, which is what sensitive electronics are designed for.

Rated for -4°F to 113°F (-20°C to 45°C). Designed for indoor use. Protect from prolonged exposure to extreme humidity or condensation.

A free mobile app that gives you visibility and control over your Pila system. Monitor battery status, see appliance energy usage, manage scheduling, and control the system remotely. No monthly subscription fees.

Pila connects two ways: to the internet, and to other devices.

For internet, Pila uses dual-band Wi-Fi (2.4 and 5 GHz). You can optionally connect over Ethernet with a USB-to-Ethernet adapter on the rightmost USB port. And every unit includes built-in 4G LTE as a backstop – if your home internet goes down, Pila stays connected for the essentials, like outage notifications and historical energy data. Note: Some app features may be limited while Pila is on cellular only.

For device communication, Pila uses Bluetooth and our patent-pending Pila Mesh Network – a secure local network that keeps your batteries talking to each other reliably, even without internet.

Yes. Pila works with Home Assistant: integrate your system to view status, monitor energy use, and build automations alongside the rest of your smart home. It's optional, built for advanced users who want deeper control.

Yes. Pila works with rooftop solar. Enphase systems communicate directly right now, so Pila tracks your real-time solar production. All that is required is communication over your home Wi-Fi to the Enphase Envoy. Direct communication integration with other rooftop systems will be added via free over-the-air software updates.

You don't need a directly supported system to benefit, though. Every Pila includes solar estimation, which predicts your production from your location and time of day, local weather, and your system's rated size – no direct connection required. Either way, Pila can factor your solar into how it charges and manages energy.

The Pila Expansion Pack adds 1.6 kWh to a base Pila, doubling your storage to 3.2 kWh. It connects through a dedicated rear port, so there's no wiring, and both batteries are managed together in the Pila App. You can reserve one with your Pila order now; Expansion Packs will ship in late 2026.

Pila's Battery Mesh Network lets you connect up to 64 batteries seamlessly today. All units appear in the Pila App as one coordinated system.

Pila does not support directly connecting third-party batteries. Third-party units cannot communicate with Pila's battery management system. To add capacity, use additional Pila units or the Expansion Pack.

However, if you have a whole-home battery system like Powerwall, there is no issue using Pila as an extra layer of protection.

Pila meets rigorous UL safety standards and includes surge protection, over-voltage monitoring, and temperature regulation. Uses Lithium Iron Phosphate (LFP) chemistry — known for thermal stability. Our team brings direct experience advancing UL and NEC standards through work on Tesla Powerwall and SPAN smart panels, and we take our product safety seriously.

Yes. Every Pila comes with a 5-year limited warranty. Full terms are on the Pila Battery Limited Warranty page.

By default, no. Pila supplies power only to devices plugged directly into its outlets and does not export back to the grid.

Pila's hardware is built for future bidirectional capability as product standards evolve. Stay tuned!

Pila is designed for indoor use. Prolonged exposure to moisture or condensation can cause damage. Do not use in outdoor or wet environments. If Pila gets wet, allow it to dry fully before use and contact support.
